Abstract
To study the control effects of terpenol extracted from Melaleuca alternifolia against tomato early blight,strawberry powdery mildew,and grape powdery mildew,the toxicity of terpenol against three crop disease was determined by pot method and semi-field experiment,and a 2-year field trial was investigated in Sichuan.The results showed that terpenol had good inhibitory effects on Alternaria solani,Sphaerotheca aphanis,Uncinula necator,with inhibitory medium concentrations(EC50)being 17.1,27.6 and 10.1 µg/mL respectively.The dosage of 9%terpenol EC was 45-135 g/hm2 to control tomato early blight and strawberry powdery mildew,and the dosage was 90-180 mg/kg to control grape powdery mildew,optimal efficacies were 86.0%,79.9%and 84.9%respectively,and it was safe for crops.Compared with the control fungicide of 80%mancozeb WP and 50%kresoxim-methy WG,there was no significant difference of efficacy from 9%terpenol EC with the highest dosage,and the efficacy was much better than 4%pyrimidine nucleoside antibiotic AS's.The botanical pesticides terpenol have good activity and field control effect against three crop diseases and can be widely applied.关键词
